New posts in Double Slit Experiment

Why does small angle approximation work for Young's double slit and not for single/multiple slits?

Differences in Double slit experiment and 2 slit Diffraction

Why does fringe width in double slit experiment remain constant if slits get narrower?

If a photon truly goes through both slits (at the same time), then why can't we detect it at both slits (at the same time)?

What do you mean by particle can be in two places at once?

Practically, how does an 'observer' collapse a wave function?

In a double slit experiment, does each and every photon leave a dot on the screen in the bright area?

How can a double slit interference pattern be created without out going through a double slit

Why aren't particles constantly "measured" by the whole universe?

In the double-slit experiment, why is it never shown that particles may hit the space between or outside the slits?
